Personally I choose to believe the first report because the second one appears to rely on snap judgements based on looking at photographs of people who are considered to be archetypically young (e.g. a baby), intelligent (e.g. Einstein) or beautiful, or their converse. It seems to me however that the primacy effect and a purely perceptual (rather than cognitive) classification plays too strong a role for that to be an effective predictor of a participant's day-to-day self image.
